Im going to the track on friday. I have a 95 z28 m6 with an slp cold air intake, bbk headers and y pipe, a holley 52 mm throttle body and a flowmaster american thunder exhaust. What should I run? Its supposed to be 62 degrees at 6 pm with humidity very high, around 85percent. Also I'm very close to sea level 200 feet maybe?

 

Anyone have an idea? Also my tires are pretty worn. What psi I'm thinking 25 or so.

Thanks

 

You asked a very open ended question. I would guess low 13's if and only if you get traction. My car is simular to your's except I have drag radials. My car would probably run 13.1x to 13.2x with 2.0 60'. Add 1.5 for each additional 60' time. So with a 2.5 60' you should run 13.80's.
